Bryndle Sibe's fursona is a light copper Siberian husky with medium length red hair. She sports glasses, a purple banded marking going around the middle of her tail, and three purple dots under her left eye. Bryndle is heterochromatic, having a blue left eye and green right eye. Her clothing varies.

The last name "Sibe" was chosen because Bryndle feared that she may be confused with a wolf, cat, or even a fox.
